<span>In order to determine the sugar molecule associated with the nucleic acid, we must first determine if the nucleic acid is a deoxyribose nucleic acid (DNA) molecule or a ribonucleic acid (RNA) molecule. We can determine this by looking at the bases in the molecule, as DNA has thymine and RNA has uracil. After the type of molecule is determined, the nature of the sugar is given by the name. DNA has deoxyribose and RNA has ribose</span>
Presidential Reconstruction
In the spring of 1865, the Civil War came to an end, leaving over 620,000 dead and a devastating path of destruction throughout the south. The North now faced the task of reconstructing the ravaged and indignant Confederate states. There were many important questions that needed to be answered as the nation faced the challenges of peace:
<span>Who would direct the process of Reconstruction? The South itself, Congress, or the President?Should the Confederate leaders be tried for treason?How would the south, both physically and economically devastated, be rebuilt? And at whose expense?How would the south be readmitted and reintegrated into the Union?<span>What should be done with over four million freed slaves? Were they to be given land, social equality, education, and voting rights?</span></span>
Answer:
a. All of these
Explanation:
<em>The characteristic of skin that makes it unpleasant for most bacteria would be due to all of the conditions.</em>
Most bacteria require humid condition in order to grow and as such, the desiccated nature of the normal human skin makes it difficult for them to establish themselves and grow on it.
The pH of the skin is usually acidic due to the production of lactic acid during sweating and the activities of the normal skin bacteria. The acidic pH hinders the growth of bacteria that can potentially become pathogenic to the skin.
Also, the skin produce antimicrobial substances at low pH which hinders the growth of pathogenic bacteria.
Hence, options b, c, and d are correct.
The answer is a missense mustation, or substitution mutation.
This type of mutation involves the substitution of one amino acid with another, resulting in the change of one DNA base pair.
Answer:
B. Habitat
Explanation:
Habitat destruction is the process by which natural habitat is damaged or destroyed to such an extent that it no longer is capable of supporting the species and ecological communities that naturally occur there. It often results in the extinction of species and, as a result, the loss of biodiversity.
